Operation Pipestone Canyon

Operation Pipestone Canyon was a US, ARVN, and South Korean military operation of the Vietnam War which occurred from 26 May to 7 November 1969.

The operation was launched to clear Go Noi Island, 15 miles south of Da Nang, which was nicknamed "Dodge City" after the Wild West town. The US Marine Corps, three battalions of ARVN rangers, and a South Korean marine brigade took part in the operation, facing NVA and Viet Cong ambushes. By the end of June, Go Noi Island was secure and Route 4 was reopened to allied traffic, but they repeatedly had to sweep through Dodge City and clear out the communist forces. The operation was ultimately a success, as Dodge City, Go Noi Island, and Route 4 were cleared of communist forces.
